Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath-structured wall body provided with a foamed resin plate and a lath net, which is completed as a wall of a building such as a detached house by spraying mortar after standing.

[0002]

2. Description of the Related Art Conventionally, in the case of constructing a wall of a building, for example, columns are erected at appropriate intervals, a plywood is struck on the columns, a lath net is attached to the outside of the columns, and mortar is sprayed on the columns. The method of spreading glass wool for heat insulation is widely known.

[0003]

However, according to the above-mentioned conventional method, when dew condensation occurs on the inside of the plywood plate due to a temperature difference, the glass wool gradually absorbs this dew condensation and deteriorates. There is a problem that it does not function as a heat insulating material. There is also the drawback that the number of construction steps is large. Therefore, a grid-like wire mesh made up of steel wires having a diameter of about 2 to 4 mm is positioned on both sides of the foamed resin plate, and a large number of beam-shaped wire mesh members penetrating the foamed resin plate are used to
It is conceivable to adopt a method of constructing a wall body by welding and fixing a sheet of grid-like wire mesh, and erecting this wall body and spraying mortar on both sides to construct a wall. It does not occur, the construction is easy because of its self-sustaining property, the number of steps can be reduced, and the strength of the completed wall is high (see, for example, JP-A-5-230897).

However, such a method of spraying mortar onto the foamed resin plate with a wire mesh is not suitable for use as a wall of a detached house because of its structure, and the cost is high. In addition, since the mortar surface has a property that irregularities are raised according to the shape of the lattice-shaped wire net, there is a problem that finishing work is inevitably required and it takes much labor.

The present invention has been made by paying attention to such a point, and an object thereof is to combine a foamed resin plate and a lath net and firmly integrate them through a reinforcing material. This makes it possible to take measures against dew condensation while ensuring heat insulation, as well as ensuring independence, reducing the number of construction steps and increasing the strength of the wall, and also realizing the construction of thin walls and attaching mortar with a uniform thickness. It is to provide a wall body that does not require finishing coating at low cost.

In this case, it is necessary to increase the adhesive force of the mortar as much as possible so that the mortar does not peel off.
In view of this, the present invention also aims to improve the attachment force of the mortar by devising the lath net attachment structure.

[0007]

In order to achieve the above object, the lath-clad structure wall body according to claim 1 has a reinforcing material embedded inside the foamed resin plate and a lath net on one side of the foamed resin plate. It is arranged such that the lath net is connected to the reinforcing member so that a predetermined space is provided between the lath net and the foamed resin plate.

According to a second aspect of the present invention, in the above-mentioned construction, the lath-clad structure wall body has a construction in which the lath net has spacers fixed to the side surfaces, and the lath net is in contact with the foamed resin plate at this spacer.

Further, the lath structure wall of claim 3 is
In the structure of claim 2, the reinforcing member is a pin extending from the spacer and penetrating the foamed resin plate in the thickness direction.

In the lath-clad structure wall body according to a fourth aspect of the present invention, a plurality of protrusions are integrally formed on the side surface of the foamed resin plate in the structure of the first aspect, and the lath net contacts the foamed resin plate at the protrusions. It has a structure.

[0011]

In the lath-clad structure wall body according to claims 1 to 4, when the wall is constructed by spraying mortar onto the lath net, since a foamed resin plate is used, dew condensation does not occur and the heat insulating property is maintained without deterioration. Will be demonstrated. Further, since the foamed resin plate and the lath net are firmly integrated through the reinforcing material, the rigidity is improved, the self-supporting property is obtained, the number of construction steps is reduced, and the wall strength is improved.
Moreover, the lath net does not come off. Further, since a lath net much thinner than the lattice-like metal net is attached to the foamed resin plate, it is possible to apply even a thin wall. Further, since a lath net having a finer mesh than that of a grid-like wire net is used, the mortar adheres with a substantially uniform thickness.

Since a predetermined space is secured between the lath net and the foamed resin plate, the mortar does not reach the back of the lath net and firmly attaches to the lath net, so that the mortar does not peel off.

This space is secured by the spacer in claims 2 and 3, and by the projection of the foamed resin plate in claim 4.
